To all lwhom t may concern.'

Be it known that I, HANS C. I-Io'riNG, a citizen of the United States, residing at Neuss, Rheinprovinz, Germany, have ins vented certain new and useful Improvements in Steaming Attachments for Pressing Machines, of which the following is a specification.

This invention relates to pressing machines, such, for instance, as that disclosed in my Patent No. 1,416,829, granted to me May 23, 1922, on an application filed Nov. 4, 1918, bearing Serial No. 261,118, and re newed Oct. 31,1921, as application No.

i 511,843, whereof thepresent application is a division. p

The object of the invention is to provide an improved means for delivering steam to one of the pressing members for heating the same, and also to provide a steaming attachment for supplying steam to the goods being pressed.

One feature ofthe invention relates particularly to the construction of the steam 5 delivery means, and, accordingly, consists in providing the pressing member, for instance, the buck or table, with a longitudinal channel into which steam is delivered, and a cover plate for said channel fitting between 3o the walls of the channel and embodying in its construction subdividing steam ports which insure uniform distribution of the steam throughout the length of the pressin surface, whence it permeates the fabric o the padding by which the pressing member is coated.

' .Another feature. relates particularly to the means whereby steam may be delivered to the steaming outlet at will, and consists 4o in providing a controllable `valve for releasing steamlto the steaming outlet, and locating this valve in a steam chamber which forms a part of the passage through which steam reaches the heating chamber of the pressing member, so that. any water of condensa-tion which flows back from the steaming passage will be regenerated into steam and driven off, and it will not be necessary to have any drain pipe for such water of 5o condensation or complications for insuring sufficient pressure through the steam outlet to insure permeation of the padding.

In the preferred embodiment, thc steaming outlet .takes its steam from the aforesaid heating chamber which surrounds its con-` trolling valve, thus permitting a common supply pipe to serve 'the heating chamber of the pressing member and the steaming outlet.

In order that the invention will be fully understood, I will proceed to describe the same in connection with the accompanying drawing, which illustrates the preferred embodiment thereof.

In said drawing- Figure 1 is a side'elevation of a pressing machine in which the several features of the invention are embodied.

Figure 2 is a front view thereof.

Figure 3 is a` vertical section on the line 3"-3x of Figure 1.

Figure 4 is a section on the line 4"--4x of Fi re 3.

igure 5 is a section on the line 5*-5* of Figures 3 and 4; and

Figure 6 is a top plan view of a portion of the steaming outlet.

10 represents the main frame carrying the support 11 for the table or buckV 12, and 13 represents a support on the frame for the swinging arm 14 that carries the pressing shoe 15. Arm 14 is operated to move the shoe 15 to and from the buck 12 by means which form no part of the present inven-Y tion. The present invention provides means for heating one of the pressing members, for instance, the buck 12, and also for releasing at will to one of the pressing members, for instance the buck 12, steam for steaming the goods being pressed. Accord-l ingly, steam pipe 16 is made to deliver-steam v throu h pipe 17, hinging joint 18, and branc 19 to the heating chamber of the pressing shoe 15, whence water of condensation escapes through pipe 20, while a branch 21 from said pipe 16 conducts steamthrough v the channel 22 and -23 to the heating chamber 24, 25, 26, 27, and 28 of the buck or table 12, whence water of condensation escapes through an exhaust pipe 29. And in addition to these heating means, or in addition to one of them, there is provided a valve 30 adapted to be operated at will by pedal 31l to deliver steam through the opening 32, pipe 33, and steam duct 34 into a channel 35 which is formed in the structure of the press-- ioo plate 36 fitting between its converging walls,l

and constructed with upwardly extending transverse grooves 37 which together with the converging Walls of the channel 35 afford escape ducts for the spraying steam that issues from the ores of the padding over the pressing mem er.

In order that waterof condensation-ow ing back through pipe 33 may be disposed of without the complication of a drain pipe which would necessitate a trap to maintain pressure at the steaming outlets 37, a collecting-chamber 38 is provided at thelower end of said pipe 33, and this is so incorporated in the walls of the chamber 22 that any water accumulating therein when the steaming attachment is not in use will be quickly vaporized and dissipated in the form of steam by the heat of the steam in the chamber 22. Y

As shown more clearly in Figure 3, the chamber 38 may have an annular extension 38 surrounding a portion of the chamber 22 to render heating effect still more etiicient. p

To facilitate construction and assembly of the parts, the valve 32 is associated with chambers 22 and 38 as the casting in which these chambers are formed affords convenient means for tapping in the several pipes 21, 23, 33, the forming of a seat for the valve 30, and the mounting of the packing gland 30 for the stem of valve 30.

The rear end of the shoe carrying frame 14 is provided with a counterweight arm 39, to which is pivotally connected a link 40, the other end of which link is pivotally connected to a lever 41 pivoted at 42 in the frame 11 of the machine. The free end of this lever 41 is bifurcated and receives between its arms a rod 43 supporting a roller 44 and a loosely mounted cam member 45 having a flat locking face 46 to be referred to later. Pivotally connected to the rear of the frame at 47 is an operating lever 48 eX- tending to the front of the machine, said lever resting upon the roller 44 so that when the levier 48 is depressed thefbifurcated end of lever 41 will be depressed for moving the pressing shoe 15 intova pressing position,in which position the lilik \and lever 41, forming a toggle, are thrown into a line with the dead center and into engagement with anadjustable stop member 49. When the shoe is in oli', or non-pressing position, the toggle members comprising link 40 and lever 41 are thrown to the other side of the critical center, and the under side of a lever 50, pivotally connected at 5I to the lever 48 `near `tlie front end thereof, rides upon the loose cam 45. However, whenthe lever'48'is deassume a locking relationship pressed and the shoe 15 is moved toward a mat-ically, regardless of the variation in the thickness of the materials being pressed, for the reason that the pivotal center 51 of the locking lever 50 'moves on the arc of a circle which is larger than the arc on which the center of the locking cam moves. That to the pivotal point 51 of the lever 50 is greater than the radius from pivotal 'point 42 to the center of the locking cam 45. Accordingly, as the lever 48 isdepressed, the pivotal center 51 of the locking lever 50 recedes from the center of the locking cam 45 and will continue to recede the further the lever 48 is depressed, and regardless of the variation of the thickness of the material being pressed, Within certain reasonable limits, the locking cam andlockinc lever will for holding the pressing shoe in a pressing position. To release the pressing shoe from locking position, the lever is repressed, whereupon the locking face 52 thereof vmoves yout of engagement with the .locking face 46 of the cam 45, it being understood that the cam 45 is free to rotate on its support. As soon.

as the locking lever 50 is moved out of lockis to say, the radius from pivotal point 4T i ing position, the pressing shoe 15 will be moved upwardly out of pressing position and the toggle comprising link 40 and lever 41 will be broken as a result of the action of spring 53, one end ofwhich is connected to an intermediate point of lever 48, the other end of which is operatively and adjustably connected to the rearwardly extending arm of theshoe carrying frame 14.
